Michael J. Callahan (1858 – December 9, 1902) was an American saloonkeeper and politician from New York.
He served in the Assembly in 1894, during which time he presented a bill to prevent the quick burial of people suspected to have been poisoned and a bill related to property on 120th Street.
[1] He declared he'd never follow the Raines law and would keep his saloons open on Sunday.
Theodore Roosevelt, at the time New York City Police Commissioner, had him arrested over it, although the indictment was dismissed when it came to trial.
His brother was Captain Daniel Callahan of the New York City Fire Department.
